GERMANIUM(IV) ETHOXIDE Usage And Synthesis
Chemical PropertiesWater-clear liquid. B.p. 186°C. Hydrolyzes easily, yielding GeO2.
UsesIt is a sol-gel intermediate for optical fibers and photosensitive.
PreparationA solution of 9.8 g. of metallic sodium in a considerable excess of absolute alcohol is prepared. A solution of 20 g. of GeCl4 in absolute ether is added with stirring and exclusion of moisture. The mixture is refluxed for several hours and then decanted from the NaCl which separates. The solid is washed with absolute ether. The washings are combined with the main solution and the solvent is then driven off in vacuum. Finally, the tetraethoxygermane is distilled. It is redistilled at atmospheric pressure.
Purification MethodsDistil it through a 10cm Vigreux column (p 11) under reduced pressure. Alternatively distil it through a Fenske glass helices (p 11) column fitted with a total condensation variable take-off stillhead. Fractionate it under reduced pressure using a reflux ratio of 10:1.
